Loox ron AUTOMOBILES.

Specification of Letters Patent.

Application filed J'uly 17, 1919. Serial No. 311,61eaifA To all whom t may concern: B e it known that I, THOMAS A. REEDER, a citizen of the United States, residing at Baltimore, in the State of Maryland, have inverted certain new and useful Improvements in Locks for Automobiles; and I do hereby declare vthe following to be exact description of the invention, such as vvill enable others skilled in the art to which it appertains to make and use the same.

.This invention relates to Wheel locks and While particularly adapted to automobile wheel locks, is not limited thereto.

An object of this invention is to provide a chock to be locked to automobile vvheels toprevent theft and v'vhich is lockedtothe wheel in such a manner as cannot be manu ally turned around and is also locked in such-a manner that the pressure uponA the automombile wheel transferred to the chock v can not cause the chock to vturn around. A

comnion trouble with the chocks that are used on the automobiles for locking 'thenrl against stealing isthat they are' easily turned around and especially'so. when the tire is flat and alsothat the automobile itself turns them around when it is started and they are thereby rendered useless;v

Efforts have been made to overcome this difliculty` by locking them to the Wheel spoke but this places undue stress upon the' spoke and also upon thelocking means and it is of this invention to overcome the chock in such a formation that it Will in itself take care of allthese stresses.

A further object of this invention is to of simple structure and one easily and cheaply manufactured and lifrht and of neat a )earance and one easilv I: y

manipulated when locking to a lVith these and other objects car.- in view the invention consists in the construction, combination, and in detail and arrangement of parts as hereinafter morefully described Fig. 2 is a perspective view showing the chock and a fragment of an automobile spoke. The chock comprises a V-shaped piece of sheet metal 1. At each end of this V-shaped 55,

piece of sheet metal are straps 2 extending a full, clear, and lV-shaped piece 1 as shown at the diameter of 'the tire.'

said around said V-shaped piece of metal. i This V-shaped piece 3 at each end and has rabbets 1--4 ofthe same circular formation as the tire yto which it is desired to attach-the same. The braces 3 are lapped under the strap 2 and overthe 5 and the three pieces are riveted together. 4The Patented Deo. 16, 1919,

of metal is joined by bracesl straps 2 are extended in extension 6 andl carry pivoted members 7.' Pivoted members ffare formed of tivo ends to carry pivoted members 7 and the other of said straps is perforated to co!v receive a lockvvith said pivoted members. This pivoted member 7 is of circular formation at 16 and adapted to open in order `e5 straps and pivoted to f extensions 6 at 9.`l One of the extensions 6v to l'allow it to be inserted around a spoke, 15.

The length-of the lsh'aped member form ing the chock proper is sli htly greater than enit comes in" engagement lwith theroad Iasthe automobile a surface greater than thediameter of the tire comes in contact with the ground andvas Wheel is being turned in case of theft, for instance, the whole face for the width of a result of this it braces itself, against turning.

to strain this sheet against the' support of. brace 3.

lith the structure of chock l to resist the turning movement under the pressure. of the pivoted member'y of the Wheel. strap 6 The angularity land thickness of the V- 7 need be only of suiicient strengthto. prevent the theft ofthe lock, whereas formerly all turning stress from angular pressure on the vv'heel was transferred to thev wheel and voke straps.

What I claim is:

1. A 'wheel chock comprising a sheet'bent f in V-shape and rabbeted to mate a tire and means for aHiXiiig said chock to a tire, the

aflix'ing means comprising straps around the ends of said chock,"sa 1d straps aiixed' to said chock, one of said straps carryinga pivoted member, and the other meneer .of sei'c fstrnps adapted to receive and leekl said p'voted member. e `l` Y 2. A wheel chock comprlsing an angle bar .bent from sheet metal and Ineens for axing` 5 said bar transversely to a wheel with chey apex ef seid bar toward the ground.

A Wheel chock comprising en ordinary v angle iron of length greater than the diemeter of a tire to which' axed and means-for xing said angle liron transversely to n' l@ Wheel with the 'apex of said iron toward the ground.

In testimony Where'f ax my signature.
